Construction at a master-planned development in northern San Diego County has restarted after a roughly two-year building stall brought on by the recession.

Two new neighborhoods are coming online Saturday at Del Sur, what will be a 3,000-plus unit project north of State Route 56 between Interstate 5 and Interstate 15.

The openings come at a time when countywide housing supply is lower than normal, buyer demand is high, and both public and private homebuilders are scrambling to acquire land to feed the demand for new product.

New activity at Del Sur also signals an upbeat attitude about the homebuilding market from Irvine-based Standard Pacific Homes, which now has total ownership of the master-planned community.

The publicly traded company, which had been a managing member of Del Sur since 2003, bought 100 percent control of the development in the fall from the original developer, Black Mountain Ranch. Black Mountain Ranch is now a company of Standard Pacific Homes, and Bill Ostrem, its president and CEO, was retained to run operations.

"We see the market continue to strengthen in traffic and sales," Ostrem said. "We're bringing out more variety of product to meet the demand."

The Del Sur deal was part of Standard Pacific's move to spend about $246 million on land and development in the third quarter to acquire 3,500 home sites.

Of those sites, 2,500 are in the San Diego market, which Standard Pacific CEO and President Scott Stowell called "supply constrained and highly coveted," in an Oct. 26 earnings call. Roughly 1,700 home sites at Del Sur remain undeveloped and are now under Standard Pacific's control, public records show.

•Carrillo by Standard Pacific Homes. These single-family homes start in the low $700,000s and feature 2,483 to 2,973 square feet. The floor plans feature car garages located on the side of the homes instead of the front and emphasis on connecting indoor and outdoor space, said Jeff Lake, Standard Pacific’s national head of architecture. At build-out, there will be 52 homes.

•Brookfield Sentinels by Brookfield Homes. Properties here range from 2,784 to 3,388 square feet that start in the $900,000s. The inspiration for these homes is Mediterranean, with features including arched colonnades and bougainvillea.

Those builders are releasing six homes at each neighborhood during the first phase.

Also under construction are three additional neighborhoods, four parks and a K-8 school that will open fall of next year, Ostrem said.
